I vote FAST Rt for the simple fact that it's basically an efi tunnel ram tuned for a truck.

If it's in the budget, you'll see much better gains with the LSXRT than a ported TBSS mani. You'll also have a better looking manifold in the end.

Could be strong but wasn't there a dyno where the ported nnbs intake out performed the xt from fast? You getting the 102 TB to match?
